COMBINED DOBBY AND \JACQUARD DEVICE.

SPECIFICATION forming part of Letters Patent No.-'7'70,112, dated September 13, 1904.

Application filed June 1, 1903. Serial No. 159,645- (N0 model.)

To all whom/zit may concern:

Be it known that I, HEINRICH REUFER, a subject of the King of Prussia, Emperor of Germany, residing at 351 Vredenerstrasse, Stadtlohn, in the Kingdom of Prussia and Empire of Germany,'have invented a new and useful Combined Dobby and Jacquard Device, of which the following is'a specification.

My invention relates to a combined dobby and jacquard device, the said dobby being designed for the bindings of the ground and the jacquard device for the figure.

In the accompanying drawings, Figure 1 is a front elevation, Fig. 2 a horizontal section on the line A B of Fig. 1, and Fig. 3 a vertical section on the line C D, Fig. l, of this combined dobby and jacquard device.

In carrying this invention into practice I provide the jacquard device as well as the dobby with a separate chain of cards or patterns K and K Both chains have, however, a common card-prism P P the prism P for the j acquardcards being larger than the prism P designed for the dobby-cards. The prism P P is adapted to turn in a holder or support, which, as is known, consists of the two arms a and a fixed upon the shaft a and connected by a transverse rod a, the said shaft (0 being arranged to swing in the side walls S S of the device. On one side the prism P P is provided in the known manner with a ratchet I), which as the prism holder or support swings outward is turned step by step through the agency of a pawl b", pivoted to the side wall S.

The prism P P is secured in its several positions by means of a spring-bufier 6 adapted to move in guides 6 I2 on the arm (0 The lifting bar or box T of the jacquard device has, for instance, six lifting-blades 0, which in the upward movement raise the lifting-wires 6 not forced back by the needles in accordance with the figure or pattern. By means of eyes or suspension-rods f f the lifting bar or box T is suspended from a carrier E, fixed in a slide T. This slide is of T-shaped form, Fig. 2, and adapted to move up and down between two Vertical guide-bars T provided on the side wall S. The carrier E has prolongations E and E extending to From the latter prolongation is arm G fixed to the side wall S.

suspended the lever F for the blades of the dobby, such lever being arranged to swing at the other end about a bolt 9, which is fastened to the free end of an arm g, provided on the side wall S. The articulated connection between the end E of the carrier and the lever F is effected by a connecting-piece fixed to the latter and furnished with an eye F for the end E of the carrier E.

At their lower ends the lifting-wires it of the dobby are connected with the rods 7:, which when the lifting-wires are lowered bear upon the board G under the wires of the dobby. The board G of the dobby is firmly connected with the board G of the jacquard device, and both boards together are fixed to a lever G This lever swings about a bolt G on an Thus both boards G and G are movable to enable, if necessary, a low shed to be formed. The dobby forms a high and low inclined shed; but the jacquard device forms a straight high shed and an inclined low shed, as indicated by dotted lines in Fig. 1.

The prism holder or support receives its movement from a shaft I, driven in the wellknown manner from the loom. This shaft is supported in the side walls S S, and fixed upon it at its end are arms ff, connected by a push-rod is or is with the corresponding arm a or a of the prism holder or support.

Upward and downward movement is imparted to the slide T, and thus to the lifting bar or box T of the jacquard device and to the lever F for the blades of the dobby from the shaft L. This shaft is supported parallel to the shaft I in the side walls S S, and secured upon it is a two-armed lever L U, the arm L of which is moved from the loom, while the other arm, L acts upon the carrier E by means of a push-rod L The boards G and G are likewise raised and lowered from the shaft L. A toothed sector M is arranged by the side of the lever L on the said shaft. With this toothed sector engages a toothed sector M, firmly connected with a lever M This lever swings upon a bolt M fixed to the side wall S, and its free end takes by a roll M below a projection G of the board G. Owing to the transmission through the toothed sectors the lifting bar or box T, with the lever F, on the one hand, and'the boards Gr G under the lifting-wires, on the other hand, make movements in opposite directions. Thus either all these parts approach or recede from the position of rest at the same time.

The combination between the two machines consists in the following:

First. The card-prisms are combined into a single card-prism, on which are the two sets of cards K and K arranged alongside of each other and each individually exchangeable.

Second. The lifting-wire boards G G are fixedly connected with each other for the purpose of obtaining simultaneous movement common to both of them.

Third. The lifting-bar E of the jacquardmachine is connected with the lever F of the dobby for the purpose of common ascent and descent of same. This makes only one driving means necessary for the parts of both machines corresponding with each other in mode of operation.

In general the two machines work always simultaneously. The dobby works the ground and the jacquard-machine the pattern.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A combined dobby and jacquard device having a single card-prism, a chain of cards for the dobby and another chain of cards for the jacquard device, substantially as and for the purpose herein set forth.

2. A combined dobby and jacquard device having a single card-prism, a chain of cards for the dobby and another chain of cards for the jacquard device, a lifting-bar for the lifting-wires of the jacquard device, a carrier from which the lifting-bar is suspended, a slide for holding the carrier, means for guiding this slide vertically, and means for moving the said slide up and down, substantially as herein set forth.

3. A combined dobby and jacquard device having a single card-prism, a chain of cards for the dobby and another chain of cards for the jacquard device a lifting-bar for the lifting-wires of the jacquard device, a carrier, from which the lifting-bar is suspended, a slide for holding the carrier, means for guiding this slide vertically. means for moving the said slide up and down, a lever for the blades of the dobby, and an articulated connection between this lever and the carrier of the liftingbar, substantially as herein set forth.

4. A combined dobby and jacquard device having a single card-prism, a chain of cards for the dobby and another chain of cards for the jacquarddevice, a board for the lifting-- Wires of the dobbyand a board for the lifting Wires of the jacquard device, the said boards being firmly connected with each other, a lever for carrying both boards, and means for moving this lever up and down, substantially as herein set forth:

5. A combined dobby and jacquard device having a single card-prism, a chain of cards for the dobby and another chain of cards for the jacquard device, a lifting-bar for the jacquard device, a lifting-bar for the dobby, an articulated connection between the same, a board for the lifting-wires of the dobby, a board for the lifting-wires of the jacquard device, the said boards being firmly connected with each other, a lever for carrying these boards, a carrier for the lifting-bar, and means for simultaneously moving this carrier and the lever for the boards under the liftingwires in opposite directions, substantially as herein set forth.

. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HEINRICH REUFER.
